  • Switch PyUnicode_InternInPlace to _PyUnicode_InternMortal, clarify docs

  • Document immortality in some functions that take const char *

This is PyUnicode_InternFromString;
PyDict_SetItemString, PyObject_SetAttrString;
PyObject_DelAttrString; PyUnicode_InternFromString; and the PyModule_Add convenience functions.

Always point out a non-immortalizing alternative.

  • Don't immortalize user-provided attr names in _ctypes (cherry picked from commit b4aedb2)
  • Issue: Interned strings are immortal, despite what the documentation says #113993

* Switch PyUnicode_InternInPlace to _PyUnicode_InternMortal, clarify docs

* Document immortality in some functions that take `const char *`

This is PyUnicode_InternFromString;
PyDict_SetItemString, PyObject_SetAttrString;
PyObject_DelAttrString; PyUnicode_InternFromString;
and the PyModule_Add convenience functions.

Always point out a non-immortalizing alternative.
